The Magician's Tower

I've seen several mentions of this, but no real information.

Anyone have a clue?

EQ button, Actions (I think), Extended Target.

Yea, I don't actually play anymore.

I'm looking for information as to what it is, how it differs from the old one.

It's essentially 5 target windows stacked in one window. You can have it set up to add mobs automatically when you show up on their hatelist or you can add specific targets to it, including pc's. It displays mob health only but during beta it displayed their mana as well lol but now it only shows pc mana. You can also save the settings like you do the spellbook so at raids and you have a tank lineup you can watch the tanks in order and know when to heal who, you can see what mobs are taking damage and target them from the ETW (extended target window) for an assist, you can set it to display the mob the main tank is fighting in a certain window, display the mob your merc has targetted, etc. There are many uses for this thing and will be even more powerful if they ever add more slots as it's only relegated to 5 slots (but the UI shows up to 10 atm if you mess with ui's any).
